He always known that the life of the strongest is not the easiest. Doesn't make it less lonelier than it is. Sometimes Satoru wishes he's just a normal person, not one born with the weight of the world upon birth. Despite it, living in reality is what he always did. There's no use in hoping for something that will never come true.
Or so he thought. Love is a foreign thing for him. With the way he's born and raised more like a glorified destructive machine than a human being, he never thought he'd be at the mercy of such insignificant feeling. He tried at friendship. Just to be stabbed in the back. He tried at mentorship or simply having colleagues, but no one can keep up with him. No one can understand him. Not like he wishes for.
He understands that his life is his alone, and expecting people to understand that is just ridiculous when people doesn't even know a bit of what he's done for the world. And at times, he convinced himself that he's fine that way. After all there's no reason to expect more.
So technically he did feel the same about love. He tried. At first. To have someone that could understand him in the way that he never received. But it feels numb overtime. Caring for one special person is tiring when he's supposed to save thousands. Eventually he found himself cannot keeping up with the emotional burden that once he gets the title of the head of the clan, he makes sure to stop any propositions that force him to choose relationship. Be it marriage or dates.
He starts to view women more of a plaything, something he can fool around with and has a short relief with. Though he mostly kept his lifestyle in secret. This doesn't mean he's a complete jerk. He still respect women, and only play around with those that offer. He never thought about taking advantage of them for being weaker than him. He doesn't want to play with one's feelings. Because love is the greatest curse of all.
But recently... He starts to realize something. It's funny at first, how it starts. You're supposed to be nothing more than an accomplice. But somehow you're the one that stay the closest and the longest. Enough to make him get this confused feelings about what you and him supposed to be. Is it really just two people sharing a complimentary goal? Or perhaps it was something deeper.
Though his mind start wavering, he didn't dare to bring the subject upfront. Fearing that what you two have currently will change if he did. You allowed him to be himself. To be just a human, not the strongest. And yet, despite your usual crudeness towards him, you didn't held any judgement when you see him let his guard down. You see him as a human. And he also starting to see as more than a friend... And that scared him to some point.
